Application filed October 25,, 1924. Serial No. 745,848.

. My invention relates to paper ruling. 1na

chinesand particularly to meansfor auto matically controlling the. driermeans so that the blanket shall not be injured thereby when the machineis stopped forany purpose Heretofore, .in the operation of paper rulingmachine, Whenever the machine is stopped and the blanket" brought torest, it is nece s ry for the. operator to cut off the drying, heater asotherwise the blanket 're-. maining stationary above the heater wouldbe" damaged or" burned. The operators are often, careless in cutting offthe heatersand theresultii's that theblankets, whichare very expensive,are frequentlydamaged.

Iha've conceived that automatic means mayf'be' provided vvhich willeither cut out the drying heater or (reduce its temperature,

Whenever the blanket is stopped so that the;

blanket, though stationary aboveit, would not be injured thereby;

More particularly, the. object of my invention is to connect a controlmec hanism forthe heater with the start and stop mechanism of the'rulingimachine in such manner that the stopping of "the machine will cutof? I the heater.,

I have illustratedmy invention as applied to a pap erfrulingmachinewhichmay be of any suitable type that shownbeing a conventionalruling machine which comprises a main framework havin uprightsl and 2Which support horizontal frame members 3 and 4. On the uprights 2 is afeed table 5 and the upper ends of these uprights project Well above theframe and carry underhung arms 6 in which a roller 7 is journaled. The

frame members 4: support standards 8 having a roller? journaled at theirtop and a roller l0 journaledat their bottom. Strings pass around. theseseveral rollers9 and. 10 and over the se ni'ent'board 12 to a roller 13near the feedtable 5. ,This arrangement is of convent onal design andvforms no particular part of my invention. The roller 13 is driven by agear 14 meshing a gear lasuitablyiefi mounted in the? frame and drivenby a slid ing clutch gear lbfhaving fast and loose members which aredriven from any suitable 'source ofpower and by any availabletransmission, this being, conventionally illustrated by, a pulley driven,gear 17. The sliding olutch'gear 16 is controlled by a clutch arm 18having a clutch engaging yoke at its lower end and haying its upper endconnected to a collar 19 fast on the clutch throw rod 20. Theclutch arm18 is mounted to rock on a bracket 21'fast on an upright 2. I provide asecond bracket 22 on said upright and pivot thereonintermediate its endsa lever 23 disposed for hor zontal movement and having one endconnectedby a link 24 with a clamp sleeve 25 applied rigidly to theclutch rod '20. 'lheother.end of the lever 23 carries a pin 26 workingin an elongated slot 27 in a T-shapednrockerjarm 28,-the ends of theT-head of said arm being connected by chains, ires orother suitableconnectors 29 and 30 With a rocker 31 made fastat its center to the'stein32' ofthe gas supply valve 33 in the valvebody 34E. This valve 33is an ordinary oneay valve for controll ng the deliveryof "gas throughthe Bunsen tube to a burner 36, there being a. p lot; burner 37connected I the gas supply ahead of the byla tube 38 with valve 33.

The nianner in which the rocker elements 31and28 are connectedcausesthem to be rotat-ed together andthe arrangement of parts is J such thatwhen the clutch rod 20 is shifted to throw out the clutch the valve willbe turned to shut off the supply of gas to the burner 36. The burner 86delivers its products ofv combustion through a cone 39 to aperforatedtube havingany desired number of in As shown, this blanketpasses between the roller 43, driven by the gear 15, and the roller 13driven by the gear 14 and hence passes about a roller 44 at the lefthand end of the machine and then downwardly and about the roller 45 atthe right hand end of the machine, and then rearwardly under the heatercoils 40 around a roller 46 on a v0:- tical frame member 47, and henceabout a roller 48 in the standards 2 and upwardly about a roller 49 andback to the roller 43. Rollers 50 and 51,, mounted in uprights 4'? and52, support the flight of the blanket about the heater coils 40.

In operation, assuming the clutch thrown to couple the drive for theblanket, the lat ter will be continuously driven as will also thestrings 11 and the gas burner will be turned on full flame. W'henever,for any reason, it is desired to stop the machine, the clutch rod isshifted in the opposite direction and this motion acts sin'iultaneouslyboth to intercept the drive to the blanket feed rolls and to turn offthe supply valve to the gas burner, thus cutting of? the drier burnerand keeping it off until the clutch rod is again thrown to start theblanket drive when the valve is again turned on full and the gas, beingignited by the pilot fl e, will again supply the heat to the coils J).By this arrangement, the heater cannot be left going while the blanketis at rest and thus the blanket is at all times automatica ly protectedagainst damage from the drier heater.

It is to be understood that the sheets of paper which are fed onto theblanket between the rolls l3 and 43, pass on top of the blankets underthe ruling appliances and then are carried along under the blankets bymeans of endless strings 53 which pass from an upper roller 54 onto theblanket and follow it about the rollers 44 and 45 to the roller andthence pass over the roller 56 and around roller 57 and return to theroller 54. They thus hold the sheets face down in passing over and faceup in passing .under the heating coils 40 and the heat in these coilswill serveto dry the ruling on the paper sheets, the latter beingdischarged at the roll 46 to a lay-boy not shown.

It is to be understood that the heater shown is typical of any availableheater and that the operation of the rocker 31 may cut off the heatentirely or lower it to a safety point where it will not damage theblankets. I claim broadly the idea of providing means which will respondautomatically to the starting and stopping of the blanket drive tointerceptheat from the drier in such manner or to such extent as willprevent damaging the blanket.

Though I have described with great particularity the details of theembodiment of the invention herein shown, it is not to be construed thatI am limited thereto, as changes in arrangement and substitution ofequivalent; may lJG made by those skilled in the art without departingfrom the invention as defined in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. In a paper ruling machine having a blanket, a drive therefor and adrying heater hav a closed pipe coil for the rodnets of com stionpassing between ights of the blanket, means to interrupt the drive tothe blanket, and means automatically re- SpODSiVG to the interruption ofthe blanket drive to cut off the heater.

2. In a paper ruling machine having a blanket, a clutch controlled drivetherefor, a drying heater having a clove-d pipe coil for the products ofcombustion passing between flights of the blanket, and connectedelements to cut off the heater sin'iultaneously with the throwing out ofthe clutch.

3. A paper ruling machine according to claim 2, in which the connectedelement will automatically restart the heater when the clutch is thrownin.

4. In a paper ruling machine, a blanket and a drive therefor having aclutch control, a drying heater con'iprising a gas burner remote fromthe blanketwith a main control valve and a pilot burner, mechanicalconnections between the gas cont-r01 valve and V the clutch controladapted to close the valve when the clutch is opened and to open thevalve when the clutch is closed, and a pipe coil. forn'iing' part of theflue for the products of combustion from the heater, which coilinterposed transversely of the machine between flights of the blanket.

5. In a paper ruling machine, a clutch con trolled drive for the blanketof the machine, a drier burner havinga heating coil interposed betweenflights of the blanket, a valve for said burner, a clutch operating rod,a rocker operably connected to and reversely movable by said clutch rod,and connections to transmitboth rocker movements to open or close thevalve, and a pilot burner for theheater.

6. A paper ruling machine according to claim 5, in which the rocker isof T-type with its connections to the burner valve formed by flexiblewire cables.

In testimony whereof I afiix my signature.
